Camera HiRISE, located on board the probe Mars Reconnaissance Orbiter, photographed the entrance to the lava tube on the Red Planet’s surface.
The new rover NASA Curiosity, which is scheduled to launch to Mars in November 2011, after run fundamental scientific problems, may try to “conquer” five-kilometer mountain in crater Gale, which is chosen as the landing site. Gale is 96 miles (154 kilometers) wide, and a 3-mile-high (5-km) mountain rises from its center.
Snow storms which occur on Mars are much more important and powerful than on Earth. The red planet has dry and cold climate for the past 3.5 billion years. Although recent studies have shown that Mars began to form small lakes, and sometimes inside the craters.
According to team of researchers led by Lorena Moskardelli from the University of Texas at Austin (USA) Martian droplike “islands” have formed deep under the water. Scientists emphasize striking similarity between the features of the Martian terrain and elongated hills on the seabed off the coast of Trinidad, confirming the hypothesis that in ancient times the northern plains of the Red Planet covered by the ocean.
